The release of Cobalt Version 1.1 includes the following enhancements:
- ParMetis 3.0
Splitting of the grid can now be weighted by processor speed. This provides equal load balancing on heterogeneous systems.
- Improvement to Viscous Flux Calculations
This provides better accuracy on general meshes
- Improved Viscous Limiter
Increased stability on poor quality meshes
- Ensight Flow Visualization
Support for N-faced polyhedral cells is included in this release. In addition, the Ensight file format has been switched from Ensight 6 to Ensight Gold
- Internal Boundary Conditions
A new class of boundary conditions has been added to Cobalt. An internal boundary condition is applied where the grid does not conform to a physical boundary. Instead, it is a user-specified region in the grid to which a boundary condition is applied. The internal boundary condition types include ‘Solid Obstruction’, ‘Vortex generator’ and ‘Screen’. Various simple shapes can be used to define an object such as a ship’s antenna. See the User’s manual for more details.
- User Coded Boundary Condition
A hook is now in place for a user to code a boundary condition, compile it and link with the Cobalt executable.
- Minor Bug Fixes
Several fixes were implemented. Most fixes were in various post-processing routines.
